Do you mean typedef in the literal sense?

Yes and no. The circle concept could be equal to the 2-nsphere concept, if you prefer. And the circle class (or template class) that implements this concept could be a real typedef of the nsphere template class.

Template typedefs aren't available until C++0x.

Yet you can do it in C++03, it's just slightly more verbose (::type). I don't see how template typedefs are related to concepts though.

Is this library still targeting the current standard?

I suppose so. It's true using C++0x would make it cleaner, but you can have the same features in C++03 for not much more verbosity.
